206 Mr. A. Alcock on the Bathyhial Fishes 



(a mature female with gravid ovaries) contained seven 

 entire individuals of 8copelus pterotus besides much debris ; 

 intestine longer than the entire body, coiled, with nine pyloric 

 appendages ; no air-bladdei*. 



Colours in life : — Dorsum dirty greenish yellow, marbled 

 with lighter shades, venter silvery white, first dorsal black. 



Total length of mature specimens 5| inches. About 

 twenty-five specimens. 



Hah. Vide Station 96. 



Family Pediculati.

 {Vide Giinther, Catalogue, iii. pp. 203, 204.) 



One small specimen from Station 96 (98-102 fathoms). 



The skin is smoother and the dermal spines less robust 

 than in shallow-water specimens, while the mouth is slightly 

 smaller and the eye rather larger ; the last character may 

 either be due to immaturity or may be a reaction to depth. 



A second small Pediculate from 1260 fathoms remains 

 outside the area of incidence of any hitherto defined genus. 

 It is closest to Oneirodes^ Liitken, and Melanoeetus, Giinther. 

 It is with some diffidence that I propose to establish a new 

 genus for the reception of a single small specimen ; but there 

 seems to be no other course. 



Paeoneirodes, gen. nov. ? 



Differs from Oneirodes, Liitken, in possessing a second 

 cephalic instead of a true dorsal spine.

When captured the form of the body was ovoid, though 

 unstable ; hardened in spirit it becomes compressed and oval. 

 The length of the head is five eighths, its greatest height 

 nine sixteenths of the total, without the caudal. The eye is 

 rudimentary, being deeply buried beneath a circular patch of 

 transparent (unpigmented) skin ; above the eye is a promi- 

 nent, coarse, procumbent spine. Mouth moderately large, its
